Corsair Hydro X Series XD5 RGB Pump/Reservoir Combo - D5 PWM Pump - 330ml Reservoir - Ten Individually Addressable RGB LEDs - Temperature Sensor - Black

Alright, buckle up because I went all in on Corsair’s waterblocks for my CPU, RAM, and pump, and let me tell you—I’m never going back to EK again. I’m talking about a triple threat here, and Corsair knocked it out of the park.First off, the price difference between Corsair and EK? Stupendous. I felt like I was getting away with a steal. But the real kicker? The pre-applied thermal pads that aren’t crap. No more scraping off factory gunk like a caveman with a butter knife; Corsair actually gives you thermal pads that make installation feel like a spa day for your PC. Life-saver? You bet!Now, I’ll admit the pump was a tad pricier than I’d have liked, but after a used one leaked like the Titanic in my rig, I wasn’t about to redo my hardline tubing. Corsair’s pump is rock solid—whisper-quiet, no drama, just cool, consistent flow like it’s training for a marathon.All in all, I purchased all three: CPU, RAM blocks, and pump, and I’m writing this single review for all of them because they’re that good. Quality is top-tier across the board, and I’m officially Corsair-converted.EK, who? With Corsair, I’m finally sleeping soundly, knowing my rig looks and performs like a million bucks without costing anywhere near that. Five stars to Corsair for water blocks that are surprisingly better, better-priced, and ready to turn your PC into an absolute liquid-cooled beast!

I have been using it for more than two years and it has been perfect. I have used it continuously for almost a year for mining cards and another year for personal use; the best Corsair product so far.

its pumping along been a month or 2 and its been working great hopefully it stays this way :D

I love the look of this res/pump combo and it's powerful too with 800/L an hour. Its mounting is pretty versatile. Downside, I wanted to monitor water temps, only to figure out if need to buy another product. Never did that and it works fine, I just got off CPU temp. I haven't had leaked problems. The build quality is alright, the plastic looks kind of cheap but overall fine. Cooling is fine, I mean it pumps the water as needed.

Does what it is designed to do. Expensive but probably well worth it considering the other options on the market.

Hasn't leaked yet. Only have run a test loop so far.

It arrived with the air tube inside the reservoir just rolling around inside of it. Which in the design of this pump doesn't actually serve a purpose anyway as the coolant is only pulled from the bottom. I'd return it, but this rig isn't just some gaming rig and I really need it back in operation ASAP. Lucky for me the flow of the pump isn't enough to bounce it around...it just sort of sits there at the bottom while on and floats at the top when the pump is off...no rattling at least. If this was an actual "D5 pump" that thing would be be bouncing all over. So don't be fooled but that like I was in my moment of need. I have tiny pumps around with a far greater flow.The outlet appears to have a large space that must filled up first before it can pump. When bleeding it, air likes to sit in this pocket and even with the reservoir full of water and the pump being the lowest part of the loop, it will not bleed or pump. Nothing is labeled on the actual pump and my first thought was the instruction manual was wrong and I had hooked up to an inlet, but you can tell it is the outlet by looking in the hole...all the inlets let you see light inside. Turning it on and off repeatedly appears to slowly get it working, but the best way is to tip it a little bit side to side. Of course I didn't learn this until I had it mounted. As of the time of this writing it is still leak testing, but I don't think this should be an issue for normal operation...just is really strange.The housing has a big seam around it that is a major leak point. They also have holes all over it to allow for different configurations I assume, but I would have just rather turned it 90° then have plugs all over it that are possible leaks. Only one of these holes is an outlet so it isn't like you can have too many configuration options anyway. You can tell that RGB was their main concern rather than making an actual pump. Though if looks are the main concern...a bunch of ugly plugs don't really fit in.
